Thank you sir, I was struggling with this lesson. Your explanation made it very easy and clear.

10:00 The points with pot. V1 would act as a single point, thereby giving Rab=(r||r)+(r||r)=r. Similarly it can be applied in the first problem too. Correct me if I'm wrong.

[IITMIAN_ABHILASH]

Thanks for your best concepts about symmetry Sir

[lexanris]

Great video 🆙👍, but how can you prove that in the VPS, the points have the same potential?

[imaamahemad]

Simple but very well explained thank you sir

[flamethrower]

Sir signals and systems when will you complete it ? Thank you for excellent teaching sir. These lectures gives strong basics sir .I'm very much thankful to you and sir please complete signals and systems

[drb.prathima]

Thank you sir ur video helped me a lot

The second example of the circle problem is also symmetrical vertically. Why is HPS considered?

[harish]

After removing the points which have zero potential difference and zero current, won't the 4 resistors of the circle be in series??

[madhavkhindri]

@nesoacademy Sir the symmetry cases are only valid if all the resistances are of same value?

[rohitverma-xwim]

Sir pls complete network as early as possible

[rohithg]

Is it applicable to different value of resistances in a symmetry (geometrical and values are not equal) circuit????

[sadhanasavkare]

sir can you please prepare videos on transient

[nimitgarg]

Kaash video dekhna ki speed 2x se bhi jyaada badha sakte toh aur acha hota

[RAVIKUMAR-xuyy]

sir signals ka remaining topic kb resume kr rahe hai??

[gnquince]

Isn't potential zero on horizontal line in horizontal symmetry ?

[gkk]

@10:00 how can you say that 2r llel with 2r since ab is not short-circuit in the given question

[siriseniprashanthreddy]

I think in the 1 example the points should be shorted

[vinay-modem]

Anyone please clear my doubt!!
Please justify that how,
Branches which are mirror image about VPS have the same current
Points which are mirror image about the HPS have the same potential

[GodUssop_]

Nice explanation but why does it happen like that??
